A Liver Electrosurgery Simulator Developed by Unity Engine

Abstract

Virtual surgery has been widely used in medical training for safety and cost reasons. The hepatectomy simulator we proposed in this paper is a virtual surgical system designed to simulate the resection of liver with electric knife. It can help medical students familiarize themselves with surgical procedures and improve their skills in repeatable training. Liver model used in this study was reconstructed from real CT images, position-based dynamics has been used to make the model deformable. By combining VR headset with force feedback device, a more realistic operating environment is presented. According to the evaluation results, users all have a positive attitude towards the usefulness and usability of the simulator. Existing problems of the simulator have been discussed in this paper, as well as directions for further research.
